Crystal lattice constants are close to other experiment results. Three kinds of chemical bonds exist among Mg and B atoms, between magnesium and boride is ionic bond and metallic bond is the predominant interaction in the layer formed by magnesium atoms. A strong covalent bond in the form of sp2 hybrid between boride atoms is the most important factors which can affect the transition temperature of MgB2. Population analysis clearly shows that electrons are transferred from Mg to B, as a result, the electron-phonon coupling in the layer of B is very strong.

It was found that the silk fibroin obtaineddirectly from anterior and middle regions of middle division of silk gland is in orderedstate, assumed to be in nematic form, but not observed in posterior region, in whichliquid silk fibroin is in coiled coil and some α-helix forms. In the middle region of middle division there is a relatively regular arrangement for the α-helix, and there is arelatively regular arrangement for β-strand and loosed α-helix in anterior region.

在熟蚕丝腺体的中部前、中段的丝心蛋白处于类向列型液晶的有序态，而中部后段中则观察不到此有序态，而是呈无规线团和一些α-螺旋结构，而且中部前中段的结构也有区别，中部中段的有序态为α-螺旋结构的相对规则聚集，而中部前段的则为β-伸展链和松散α-螺旋结构的相对规则聚集。

During the first 30 years since Chinas foundation, the social interest structure was forming and remaining the singular interest body through a series of institutionalized administrative measures, which occupied the interest room. Though it remained relatively steady, it lacked the motive force of social development.

新中国成立后前30年的社会利益结构由于通过一系列制度化的行政措施形成并维持着一元利益主体，这种利益结构挤占了各利益主体的利益空间，虽然保持了结构的稳定，但缺乏社会发展的动力，这样的社会利益结构无法长久持续下去。

Represent by the enterprises strategic position in strategic group. In empirical study, the paper makes the main enterprises action and reaction index in steel industry based on the data from Jan of 2001 to Dec of 2004 of www.mysteel.com and www. steelinfo.com.cn, which are trade website in steel industry. Analysis from more than 500 actions and 2000 reactions, we verify hypothesis by statistical method.
